WAGON-=JACK AND STEP-LADDER COMBINED.

EPECIFICATIQN forming part Of Letters Patent NO. 328,701, dated October20, 1885. Application tiled September 2, 18%5. Serial No. 175,997. (Nomodel.)

To aZZ whom it may concern.-

Be it known that I, FRANK N. MOKEAN, of Long Branch, in the county ofMonmouth and State of New Jersey, have invented certain new and usefulImprovements in a Combined \Vagon-Jacl; and Step-Ladder, of which thefollowing is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similarletters of reference indicatecorresponding parts in all the figures.

Figure 1 is a perspective View of one of my combined wagon-jacks andstepladders,shown as folded for storage or transportation. Fig. 2 is asectional side elevation of the same, illustrating its use as awagoirjack. Fig. 3 is a sectional side elevation of the same, shownarranged as a step-ladder.

The object of this invention is to provide combined wagon-jacks andstepladders constructed in such a manner that they can be readilyadjusted for either use, and will be convenient and reliable with eitheradjustment.

The invention consists in the construction and combination of thevarious parts of .the combined wagonjack and stepladder, as will behereinafter fully described and then claimed.

A represents two bars,which are connected by parallel bars B ofsufficient width to serve as steps, and which are slightly inclinedlaterally to give them a horizontal position when the device is used asa step-ladder.

O are frames of unequal length, which are pivoted to the bars A at alittle distance from their ends. The other ends of the frame Carepivoted to and between two bars, D, at a little distance from theirends, so that the said bars D can be folded down upon the bars A forstorage or transportation, as shown in Fig. 1, or can be raised abovethe said bars A when the device is to be used as a wagon-jack, as shownin Fig. 2, the hinged frames C taking a nearly vertical position.

E are two frames,which are connected with each other by hinges F, sothat they can fold together, as shown in Fig. 1, and will abut againsteach other and serve as a rigid brace when the device is arranged as awagon jack, as shown in Fig. 2.

The outer end of one of the frames E is pivoted to the bars D at alittle distance from the end of the longer frame 0. The outer end of theother frame E is pivoted to the middle parts of the bars A.

To the ends of the bars D are hinged or otherwise secured handles G, forconvenience in operating the device when used as a wagonjack, and whichare adjusted against the outer sides of the said bars D, and secured byspringcatches H or other suitable means when the device is folded andwhen it is adjusted for use as a step-ladder.

The pivots of the shorter frame 0 are placed in slots I in the bars A,and are secured in the outer ends of the said slots,when the device isfolded and when it is used as a wagon-jack, by pins J, inserted in holesin the said bars A and crossing the slots I near their outer ends.

To the adjacent edges of the ends of the bars A D, nearest the slots I,are attached staples or eye-plates K, to serve as hinges when the device is adjusted as a step-ladder, the pintles of the said hinges beingthe pins J, which,with this adjustment, must be withdrawn from the barsA, so that thepivots of the shorter frame 0 can slide inward in theslots I, to allow the ends of the bars A l) to be brought together, asshown in Fig. 3.

\Vhen the device is to be used as a wagonjack, the handles G areextended and the device is pushed in beneath both axles of the wagon andthe bars D are drawn back by means of the handles G, the pivoted frames0 causing the said bars D to rise against and raise the said axles,lifting all the wheels from the ground at the same time, the said bars Dbeing locked in a raised position by the hinged frames E.

Vhen the device is to be used as astep-ladder, the pins J are withdrawnfrom the bars A, the pivots of the shorter frame 0 are moved inwardalong the slots I, to bring the ends of the bars A 1) into contact, andthe said pins J are inserted in the eyes of the staples or eye plates K,the hinged frames E taking a partly folded position, and the longerframe 0 serving as a connecting-brace, as shown in Fig. 3.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a combined wagon-jack and step-lad- 5 der,the combination of thetwo bars A, having inclined connecting-bars B and longitudinal slots I,the two bars D, the frames 0, having unequal lengths and pivoted to saidbars A D, and the frames E E, hinged to each other and pivoted to thesaid bars A D, substantially as herein shown and described, whereby themechanism can be used as a wagon-jack or a step-ladder, as set forth.

2. In a combined wagon-jack and step-lad- 15 der, the combination, withthe ends of the bars 3. In a combined wagonack and step-lad- 2o 'der,the combination, with the bars D, of the extensible handles G,substantially as herein shown and described, whereby the said handlescan be projected when the mechanism is to be used as a wagon-jack, asset forth.
